Mw Y IMPRiOVED MACHINE FOR CUTTING FAT, cc.

bw-*M*- The Schedule referred to in these Letters Patent and making partof the same To all whom vit may concern:

Be it known that I, ADOLPH PFAFF, of the city and connty'of Baltimore,in the Stateof llaryland,`

, to enable those skilled in the art to which my invention appertains tomake and use the same, reference being had to theaz'companying drawingmaking part of this specification, in whiche Figure 1 is a centralvertical section.

'Figure 2 is a top view.

, Figure 3 is an end view.

The nature of my invention consists` in a peculiarl arrangement andoperation of devices for cutting fat, 85e., first into slices, then intostrips, and finally into squares or cubes, and delivering them int-ovareceptacle prepared forthem.

In a'lcox4 or casing, A, made of any suitable form and dimensions, .andot' any suitable material, a shaft, B, is jonrnaled, and attached tothis shaft is a series of circular knives, O. Y

At a suitable distance from, and parallel with, the shaft B, is anothershaft, D, provided with a cylinder, E, having on Iits face a set ofgrooves, c, at distances corresponding with the distance apart of theknives C, and so placed that the kniveseuter the grooves as they revolvetoward each other, as indicated by the arrows. f

Just below t-he shafts B and D are-two shafts, H `and K, placed at rightangles with those above them.

On` the shaft H is a series of knives, I, arranged like those abovedescribed,` and on the shaft K is a cylinder, J, having grooves j formedon its face, and the knives I and groovcd cylinder J engage with'eachother inthe manner above described. The bearings for the journals of theshafts B, D, H, and K are elongated, as shown at lin fig. 1, so that,when the knives and cylinders become worn, they may he adjusted nearerto each other.

The cylinders E and J may be made of wood or metal, as desired.

They are provided with small pinsor project-ions 1), to assist incarrying down the fat, 86e., as they revolve.

The knives 0 are provided with a cleaning device,' M, consisting ofapiece of wood or metal, with slits formed in it, and placed so as toclean the knives as' they revolve, after cutting the fat, Ste.

lBelow the shafts H and K is a tube or trough, O, the inner end of whichis near the point of contact of the knives I and cylinder J From thencethe trough is curved downward and outward, and terminates at one end orside of the box or casing A.

The upper side of the trough O is formed with slits which serve to cleanthe knives I.. Y

On a shaft, R, which may hethe ina-in or drivingshaft, is a knife, S,attached atits center, so as to form two curved blades, as shownv iniig. 3, and arranged so as 'to pass the outer end of the trough O atevery revolution.

A cleaning device is also provided for this knife, and may consist of apiece of wood or metal, with a slit formed in it, placed so that theblades will pass through the slit at every revolution.

The shafts B, D, H, K, and O are connected by suitable spur-and-bevelgearing, so as to operate simultaneously.

The operation is as follows:

The fat, &c., is fed into the hopper V, where it is carried down by thecylinder E, and is cnt intoslices by the knives C. The slices then fallupon the cylinder J, and the knives I cut them at right angles, formingstrips.` The strips then pass into the trough O, and, as they are forcedont at `its end, they are cnt into squares or cubes by the knife S, andyfall into a suitable receptacle prepared for them.

Vhat I claim as new, and desire to secure by Letters Patent', is

1. The series of revolving knives C and revolving block E, withprojecting points p and grooves e, in combination with shafts B and D,frame A, and crankV R, constructed and arranged as shown and described.2. The series of knives I, in combination with cutrting-block J and j,with its cleaner M, as shown and described.

3. In combination with the above, the revolving S-formed knife S, theconducting-trough O, in combination with the devices for impartingmotion, all as shown and described.
